The possibility to use limited PHP scripts was added for uCoz users in March 2011.

PHP is introduced for our users to have wider possibilities of website customization. In this way the websites will become more flexible and filled with various useful features. New functions will help to fulfill various tasks on the website, to use scripts for system modules interaction and data display in a proper place, their conversion. Opportunities of releasing unusual services on your websites will become available.

This solution won't work for portal system setup, monstrous forums and other high load scripts with a non-optimal source code. They create huge and useless load on the server.
